What is strip-json-comments?

The strip-json-comments package allows you to strip comments from JSON content, making it possible to use comments in JSON files or strings for development purposes without violating the JSON format specification. This can be particularly useful for configuration files or complex JSON data where comments can provide valuable context or instructions.

What are strip-json-comments's main functionalities?

Strip comments from JSON string

This feature allows you to remove both line (//) and block (/* */) comments from a JSON string, making it a valid JSON format. The code sample demonstrates how to use the package to strip comments from a JSON string containing both types of comments.

"use strict";\nconst stripJsonComments = require('strip-json-comments');\n\nconst jsonWithComments = '{\n\t// This is a comment\n\t"foo": true\n}';\nconst cleanedJson = stripJsonComments(jsonWithComments);\n\nconsole.log(cleanedJson); // {\n\t\"foo\": true\n}"
